1997 subaru outback

Default ticking issues

I have a 1997 subaru outback with a 2.5 liter in it. For a year or so now it has made this constant ticking noise coming from the engine. At start up it's most noticable, almost sounds like a squirrel in a running in a cage. I beleive that it's the lifters but not sure, it will continue the entire time I'm driving it, but eventually grow faint. Also it's almost always present when I accelerate after it has been warmed up. Is this a usual sound and the lifters are just loose or should I have it fixed, if its the lifters at all? Also I read something about the timing belt adjuster does anyone know how I check that?

A mechanics stethascope. Start the car and listen to the front of the timing cover about 1 inch to the right of the crank pulley. While you're at it listen to the valve covers and each side of the block. You can also listen to the injectors.

Sears and carquest have them. I'm sure other places have them too. These can also help isolate bad idler bearings and water pump failures, alternator,p/s pump,and other rotating objects. Sometimes you can use it to find vacuum leaks/hissing.

It's a simple tool that really removes alot of guessing.

Get one.
